5. Installatie en installatie
5.1 Montage
- Choose a suitable location for mounting the controller, away from direct heat sources, moisture, and vibrations.
- Zorg voor voldoende ventilatie rondom het apparaat.
- Cut a rectangular opening in the panel according to the controller's dimensions (refer to the product diagram for exact measurements).
- Insert the controller into the opening and secure it using the provided mounting clips.
5.2 Bedrading
WAARSCHUWING: Zorg ervoor dat de stroom is losgekoppeld voordat u de bedrading aansluit.
- Voeding: Connect the main power supply (L and N) to the designated terminals on the controller.
- Temperatuursensor: Connect the NTC temperature sensor to the sensor input terminals. Ensure correct polarity if applicable. The sensor should be placed in the area where temperature needs to be monitored and controlled.
- Compressor Output: Connect the compressor's power line to the compressor relay output terminals.
- Defrost Heater Output: Connect the defrost heater's power line to the defrost relay output terminals.
- Ventilatoruitgang: Connect the evaporator fan's power line to the fan relay output terminals.
Refer to the wiring diagram printed on the side of the controller or in the specific model's manual for precise terminal connections.
6. Gebruiksaanwijzing
6.1 In-/uitschakelen
- To power on, connect the main power supply. The display will show the current temperature.
- To power off, disconnect the main power supply.
6.2 Viewing temperatuur
The current measured temperature is continuously displayed on the front panel.
6.3 Parameters instellen
The controller allows adjustment of various parameters such as setpoint temperature, differential, defrost cycle, and fan operation. The exact procedure may vary slightly by model, but generally follows these steps:
- Houd de INSTELLEN/OK button for 3-5 seconds to enter parameter setting mode.
- Gebruik de UP En OMLAAG buttons to navigate through the parameter codes (e.g., F1, F2, P1, P2).
- Pers INSTELLEN/OK naar view de waarde van de geselecteerde parameter.
- Gebruik de UP En OMLAAG knoppen om de waarde aan te passen.
- Pers INSTELLEN/OK again to confirm the new value and move to the next parameter, or press and hold INSTELLEN/OK to save all changes and exit the setting mode.
Common parameters include:
- Set Point (SP): De gewenste temperatuur.
- Differential (Hy): The temperature difference between the set point and the turn-on/off temperature.
- Defrost Cycle (Id): Interval between defrost cycles.
- Defrost Duration (Ed): Length of the defrost cycle.
- Fan Control (Fc): Settings for fan operation during refrigeration and defrost.
7. Onderhoud
7.1 Reinigen
- Regularly clean the front panel with a soft, damp doek. Gebruik geen schurende reinigingsmiddelen of oplosmiddelen.
- Ensure the ventilation openings are free from dust and debris to prevent overheating.
7.2 Sensor Check
- Periodically inspect the temperature sensor and its wiring for any damage or corrosion.
- Ensure the sensor is securely placed and making proper contact.
8. Probleemoplossing
| Probleem | Mogelijke oorzaak | Oplossing |
|---|---|---|
| Display shows "EE" or "HH" | Sensor error or temperature out of range. | Check sensor connection and wiring. Replace sensor if damaged. Ensure temperature is within operating range. |
| Controller gaat niet aan | Geen stroomvoorziening of verkeerde bedrading. | Controleer de stroomaansluiting en het volume.tage. Check wiring according to diagram. |
| Compressor loopt niet | Temperature not reaching set point, compressor delay, or wiring issue. | Check set point and differential. Wait for compressor delay. Verify compressor wiring. |
| Onnauwkeurige temperatuurmeting | Sensor placement, sensor damage, or calibration needed. | Relocate sensor to a representative area. Check sensor for damage. Refer to manual for calibration procedure if available. |
